> No ping/pong Author here. Are you referring to the ping/pong message frames in the WebSocket transport protocol, or just a general heartbeating protocol layered on top of WebSockets? If it's the former, then there's

Author here: That's a good feature request. I shall implement a truncating exponential backoff algorithm tonight (maybe tomorrow). I've been using this in production for over 2 years and my load levels have not caused any usabilit

Socket.IO is awesome, but my understanding is that Socket.IO also requires server side components as it adds a layered protocol on top of the WebSocket transport.

I don't recommend any kind of input parsing in a shell script. You're better of having websocketd fork something like Python, Ruby, Perl, PHP, etc. Like CGI, websocketd will pass additional URL path and query parameters as environ

It solves the problem of users having an older version of Go installed on their system. For example, if they installed it via apt-get.

huhtenberg: I believe AsymetricCom was referring to being able to compile an executable using perlcc. He wasn't referring to the networking aspects of it (WebSockets have not been around 10 years). huhtenberg: You're right. It&#x2

Author here. 2 reasons. 1. So developers can do a clean checkout and it will just work. No external dependencies needed (e.g. manually installing Go, setting GOPATH etc). 2. To ensure that anyone who builds and releases it always uses the e

It's similar to netcat -e and inetd, except it also handles the WebSocket protocol (negotiating the handshake and message framing), so your apps don't need to.

Author here. Indeed! The very first version of websocketd was actually written in Node. It's great for this kind of stuff. The reason I switched to Go was to make distribution/installation for end users easier.

Author here. If you use this on top of programs like bash, well ermm, you get what you deserve ;). Here's an example of how I used websocketd to create a little dashboard for monitoring Linux CPU/memory/IO stats. It basically

OP nailed it. PHP has similarities to Bash scripting. Language sucks. Syntax is awful. You wouldn't want to build anything big with it. You feel dirty and ashamed every time you use it. But... if you just want to get shit done, it&#x27

Indeed it is just a breakout board. It's really just to make it more convenient to connect peripherals. I've found for simple things like LEDs, buttons and some I2C components you can get away without additional protection. I should probab
